Safety Valves on Silo are products designed to ensure that the pressure of the silo returns to normal by opening in case the pressure increase during the filling of silos, which are industrial storage units, reaches the risky point. Silos are similar in shape to pressure vessels, but they are not considered pressure vessels in terms of materials used, manufacturing methods and quality tests. For this reason, measures should be taken against the increase in internal pressure and damage to the silo should be prevented. During the filling of the silo, the transport air together with the powdered material must be transferred from the filter on the silo. If the filter cannot perform this function properly (filter cartridges are clogged, maintenance is not done in time, it is defective, etc.), the internal pressure of the silo rises. In such cases, the Safety Valve on the Silo, which does not need electricity with its mechanical structure, has a duty and in case the set value is exceeded, it opens and evacuates the excess air inside the silo. Thus, the internal pressure of the silo is balanced. These products, which can be called by different names such as Silo Safety Valve, Silo Pressure Relief Valve, Silo Air Discharge Outlet, are supplied as standard with connection flange to the silo and all air passage surfaces are manufactured with gaskets.
